Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a shelf device for a refrigerator or the like that is constructed of both front and rear shelves and is extendable and retractable.

[Technical background of the invention]

This type of shelving device, for example, has a front shelf and a rear shelf each constructed with a substantially rectangular shelf frame with a large number of support bars installed in the front and rear, and both shelves are arranged such that the rear frame of the front shelf is connected to the support bars of the rear shelf. There is a structure that is arranged in a refrigerator in such a way that the front frame of the rear shelf is located below the support bar of the front shelf. In this case, by moving the front shelf rearward, the upper and lower partitions created by the front shelf can be eliminated, so it is convenient to be able to place, for example, tall bottles on the lower shelf.

[Problems with background technology]

However, with the conventional structure described above, when the front shelf is pulled out fully forward and extended in normal use, the front shelf is not restrained in any way and easily moves rearward, so that no storage is stored on the shelf. There was a drawback that the front shelf moved inadvertently when putting things in and out.

[Purpose of invention]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a shelf device for a refrigerator or the like that can prevent the front shelf from moving inadvertently in the extended state.

[Summary of the idea]

The present invention provides a connector on one of the rear frame of the front shelf and the front frame of the rear shelf that detachably engages with the other when extended, and connects the front shelf and the rear shelf when extended. However, it has certain characteristics.

[Example of idea]

An embodiment in which the present invention is applied to a refrigerator shelf device will be described below with reference to the drawings. First, in FIG. 1, reference numeral 1 denotes a refrigerator outer box, inside of which are formed, in order from the top, a freezer compartment (not shown), a refrigerator compartment 2, and a vegetable compartment (not shown). Reference numeral 3 refers to a sliding shelf that is arranged in two stages, upper and lower, in the upper part of the refrigerator compartment 2 and can be pulled out to the front. It is a shelving device. This shelf device 4 is constructed as shown in detail in FIGS. 2 to 10. That is, 5 and 6 are a front shelf and a rear shelf, respectively, which constitute the shelf device 4;
The front shelf 5 includes a front frame portion 7 and a rear frame portion 8 that both extend left and right.
The rear shelf 6 is constructed by constructing a large number of support bars 9 extending back and forth between them, and the rear shelf 6 has a large number of supports similar to the front shelf 5 between the front frame part 11 and the rear frame part 12 of a rectangular frame body 10 made of steel wire. It is constructed by installing support bars 9 in the front and back. The rear frame portion 8 of the front shelf 5 is positioned below the support bar 9 of the rear shelf 6, and the front frame portion 11 of the rear shelf 6 is positioned below the support bar 9 of the front shelf 6. By relatively moving both shelves 5 and 6 back and forth, it is possible to change the state between the extended state shown in FIG. 2 and the contracted state shown in FIG. 10. This shelf device 4 also includes slide buttons 13 (only one shown) provided at both ends of the decorative front frame 7 of the front shelf 5, and a left frame 10a and a right frame of the rectangular frame 10 of the rear shelf 6. (not shown) are placed on shelf receiving protrusions 14 protruding from both left and right inner walls of the refrigerator compartment 2 so as to extend back and forth, so that each shelf 5, 6 can be slid back and forth. There is. 15 is a rising portion formed by bending the rear end of the support bar 9 of the rear shelf 6 upward;
When the front shelf 5 is pulled out forward so as to be located outside the refrigerator compartment 2, it comes into contact with stoppers 16 protruding from both the left and right inner walls of the refrigerator compartment 2, and prevents the refrigerator compartment 2 from being pulled out any further forward. 17 is a connector made of an elastic material such as plastic, which has a narrow opening 18 at the bottom as shown in FIGS. 3 and 4.
a substantially cylindrical mounting portion 19 having a
The mounting portion 19 includes a substantially half-cylindrical elastic engagement portion 20 that is integrally formed in front of the mounting portion 9 and opens upward.
is attached to the rear frame portion 8 of the front shelf 5 by elastically fitting it through the narrow opening 18. In this attached state, the abutting piece 21 integrally provided on the upper part of the attaching part 19 and protruding rearward comes into contact with the support bar 9 of the rear shelf 6 from below, and the connecting member 17 is brought into contact with the arrow A in FIG. It is designed to prevent rotation in that direction. Reference numeral 22 denotes a guide piece extending diagonally downward in front of the elastic engagement part 20, and this guide piece comes into contact with the front frame part 11 of the rear shelf 6 when the front shelf 5 is moved forward from the contracted state of the shelf device 4. This guides the elastic engaging portion 20 to expand elastically, thereby causing the elastic engaging portion 20 to engage with the front frame portion 11. Reference numeral 23 denotes a hanging device, which is connected to a narrow opening 24 as shown in FIG.
A pair of substantially cylindrical mounting portions 25, 25 having the same structure are integrally connected by an inverted U-shaped sliding portion 26, and the sliding portion 26 is placed over the support bar 9 of the rear shelf 6 from above. Attach the mounting parts 25, 25 to the rear frame part 8 of the front shelf 5.
When the shelf device 4 is in the contracted state, the sliding part 26 is supported by the support bar 9 of the rear shelf 6, so that the rear frame part 8 of the front shelf 5 is held in a suspended state. It is. In addition, this hanging tool 23
When the shelf device 4 is in an extended state and the elastic engagement portion 20 of the connector 17 is engaged with the front frame portion 11 of the rear shelf 6, the sliding portion 26 and the rear shelf 6 are connected to each other as shown in FIG.
A gap B is created between the support bar 9 and the support bar 9.

Next, the operation of the above configuration will be explained. First, in the extended state shown in FIG. Both rear shelves 5 and 6
are in a state of integral connection. Therefore, even if a backward force is applied to the front shelf 5 when storing stored items on the shelf device 4, the front shelf 5 will not move rearward inadvertently, making it extremely convenient to use. Furthermore, when the front shelf 5 is pulled toward you from the state shown in FIG. (See Figure 7). In this way, it is possible to easily place and take out stored items, and even in this state, both the front and rear shelves 5,
6 are connected, it is possible to prevent the front shelf 5 from moving inadvertently. Further, when the decorative front frame portion 7 of the front shelf 5 is pushed rearward from this state, the entire shelf device 4 moves rearward without being disconnected by the connectors 17 and returns to the state shown in FIG. 2. At this time, by pressing the front shelf 5, a force is applied to the elastic engagement portion 20 of the connector 17 from the front frame portion 11 of the rear shelf 6 to rotate the connector 17 in the direction of arrow A in FIG. However, since the abutment piece 21 of the connector 17 abuts the support bar 9 of the rear shelf 6 from below and is prevented from rotating in the same direction, the elastic engagement portion 20 of the connector 17 is prevented from rotating in the same direction. The engagement is maintained, so that the rear shelf 6 moves rearward together with the front shelf 5 while the shelf device 4 remains in its extended state. In order to change the shelf device 4 from the extended state shown in FIG. 2 to the contracted state shown in FIG. 10, the following procedure is performed. That is, first, lift the front part of the front shelf 5 a little. As a result, the rear frame portion 8 of the front shelf 5 is moved to the sliding portion 2 of the hanging tool 23.
6 and the support bar 9 of the rear shelf 6. At the same time, the connector 17 also moves downward, so that the contact piece 21 of the connector 17 and the support bar 9 of the rear shelf 6 move downward. 9, a gap C is created between the two (see FIG. 8). After this, when the front shelf 5 is pushed lightly backward while the front shelf 5 is in the upright position, a force is applied to the elastic engagement part 20 of the connector 17 from the front frame part 11 of the rear shelf 6 to rotate the connector 17 in the direction of arrow A. As a result, the connector 17 rotates in the direction of arrow A until the contact piece 21 contacts the support bar 9, and the engagement of the elastic engagement portion 20 with the front frame portion 11 becomes shallow. (See Figure 9). Then, by further pressing the front shelf 5, the elastic engagement part 20 is slightly elastically expanded and deformed, and is completely disengaged from the front frame part 11. Thereafter, the sliding portion 26 of the hanging tool 23 slides backward on the support bar 9 of the rear shelf 6 and reaches the contracted state shown in FIG. 10. If an open part is formed at the front of the shelf device 4 in this way, tall bottles or the like can be stored on the lower refrigerator bottom shelf 2a by positioning the upper part in this open part.

[Effect of idea]

As described above, the present invention is assembled by installing a large number of support bars in the front and back between the front and rear frame parts, and positioning the other side frame part of one shelf frame below the other support bar. In a device comprising both front and rear shelves, each of which is configured to be extendable and retractable by moving back and forth, one of the rear frame of the front shelf and the front frame of the rear shelf has a structure in which when the other is extended, the other It is characterized by the provision of a connector that removably engages with the front shelf.As a result, when the front shelf and rear shelf are extended, the front shelf and the rear shelf can be integrally connected. To provide a shelf device for a refrigerator or the like that is easy to use and can prevent shelves from being moved inadvertently.
